基于分散加载技术的单片机增量升级程序设计

Design of incremental upgrade program for single-chip microcomputer based on distributed loading technology

目前,智能终端设备的系统升级,漏洞修复、功能拓展逐渐成为终端设备的迫切需求。因此,文章提出了一种新的单片机增量升级方法,该方法通过分散加载技术将需要升级的代码分解成独立的工程,后期只需要通过修改该独立工程的代码并编译覆盖原来的代码,即可实现增量升级。升级效率更高,对硬件资源几乎没有任何要求。

At present,system upgrades,bug fixes,and function expansion of smart terminal devices have gradually become urgent needs for terminal devices.Therefore,a new incremental upgrade method for single-chip microcomputers is proposed.This method uses scatter loading technology to decompose the code that needs to be upgraded into independent projects,and later only needs to modify the code of the independent project and compile and overwrite the original code.Achieve incremental upgrades.The upgrade is more efficient and hardly requires any hardware resources.
